PURPOSE: An apparatus for sensing obstacles and derailment is provided to automatically stop an unmanned railway vehicle in the event of a collision between the railway vehicle and obstacles or rails. CONSTITUTION: An apparatus for sensing obstacles and derailment comprises a sensing bar(100), a sensor unit(200), and a sensing bar support plate(300), and an elastic spring. The sensing bar is installed to be displaced in case of a collision against obstacles and or a collision against rails due to derailment. The sensor unit produces a contact signal when the displacement of the sensing bar is over the set value. The sensing bar is supported on the lower side of the sensing bar support plate and the rotary shaft is fixed to the upper side of the sensing bar. An end of the elastic spring is connected to the upper side of the support plate while the other is connected to a tension control device so as to support the support plate. The sensing bar support plate rotates around a rotary shaft when the sensing bar is displaced. The sensor unit generates a contact signal when the rotation displacement of the rotary shaft connected with the sensing bar is over the set value. |
